  • Multi-layer waveguide structure having spaced apart first and second signal units of different widths and heights
    Patent number: 8497742
    Abstract: A waveguide of a multi-layer metal structure and a manufacturing method thereof are provided, the method including applying a plurality of metal layers on a substrate and a plurality of insulating layers respectively between the respective metal layers. Accordingly, it is possible to minimize conductive loss by dispersing current uniformly through wide regions between a signal line and ground lines.
